What is recirculation?
Why is it required
Talk about Ammonia and Nitrates being generated from
Excess Feed
Fecal Matter
Water needs to be re-circulated to avoid
Death of Fish
How often water needs to be recirculated

5. Conventional systems – problems Needs large quantities of water

6. Conventional systems -problem
Reduced survival rate

7. Conventional systems-problems
Causes water pollution

8. Oriental Aquamarine Biotech India Private Ltd - Coimbatore
Technology developed by National Centre for Aquatic Animal Health, Cochin University of Science and Technology, Kerala, India
Technology commercialized by Oriental Aquamarine Biotech India Private Limited, Coimbatore, Tamil Nadu

9. The Solution – Bacterial Consortium
A consortium of nitrifying bacteria have been identified which break down the ammonia and nitrites
Consortium grows as biofilm on beads packed and remove Nitrites & Ammonia inside a bioreactor

30. Nitrifying Bioreactor - Advantages
Improved quality of fish produced (Organic)
Increase in fish survival rate
Increase in rate of growth and the size of fish
Better resistance to diseases
Reduction in production costs
Improvement in surrounding environment

31. Nitrifying Bioreactor - Technology
Patented technology
First of its kind in the world
Maintains reef-like conditions in aquaculture tanks
Can be used for any level of salinity
Fresh Water
Salt Water
Brackish Water
Can be used to farm a variety of marine animals
Shrimp
Ornamental Fish
Crabs/Lobsters

32. BENEFITS
Maturation (Developing ovary in the animals reared in the recirculating system)

33. Brood-stock Maintenance and Rearing
Increased stocking & survival rate

34. RECIRCULATING AQUACULTURE SYSTEM
Location flexible – transport costs minimized
Fewer tanks – less capital outlay
Temp and other parameters controlled
Planned production schedules, control supplies of fingerlings to target seasonal market demand by cage farmers Lower mortality, improved FCRs
RAS allow diversification of the farmed species base for the market substituting seafood imports and opening new markets in live fish sales
